Abstract

Termite, is one of the most damaging pest for wood product. One of the common fumigant use to control termite is sulfuryl fluoride. The objective of this study were to determine the dose-exposure and time for sulfuryl fluoride to kill dry wood termite Cryptotermes cynocephalus Kemner and evaluate the ability of fumigant to penetrate a rubber wood block. Application and penetration of the fumigant was tested on a 10 cm depth wood block, and conducted with 5 varied doses (10−30 g/m3) and 4 varied exposure time (6−24 hours). Application of the fumigant were tested on an 5 and 2.5 cm depth wood block. Doses were applied using 4 (four) different doses (2−15 g/m3) and 4 varied exposure time (1−9 hours). The study was conducted using randomize completely design with factorials. Results showed the application of sulfuryl fluoride was effective in penetrate 10 cm depth of wood block. The dose that was effective was of 30 g/m3 with 18 hours exposure time or a dose of 15 g/m3 with 24 hours exposure time. Application of depth penetration of 5 cm effectively done by using a dose of 10 g/m3 with 9 hours exposure and depth penetration of 2.5 cm using a dose of 15 g/m3 with 6 hours exposure time. Dose-time relationship for application of sulfuryl fluoride to penetrate of 10 cm showed dose variable is a slightly more important than exposure time, while to penetration of 5 and 2.5 cm showed exposure time variable is a slightly more important than dose of fumigant.

Abstract

Parasitoid Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) was introduced into Indonesia in early 2014 to control the cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). The objective of study was to determine encapsulation rate of parasitoid A. lopezi by various host instars of P. manihoti. Observation of encapsulation rate was made  by exposing a single mated female of parasitoid on mealybug nymph-1, -2, -3, and adult in a plastic cage for 24 h. Mealybugs then were dissected and number of parasitoid eggs laid and those encapsulated were counted. Study revealed that rate of aggregate encapsulation was highest (8.4%) by adults, followed by nymph-3 (5.8%), nymph-2 (3.1%), and nymph-1 (1.1%). Rate of effective encapsulation by adults was 2.0%, whereas by nymphs about  1.0%. The low rate of encapsulation is believed not to reduce the effectiveness of parasitoid A. lopezi in the biological control of cassava mealybug P. manihoti in Indonesia.

Abstract

Bemisia tabaci (Gennadius) is an important horticulture pest and is know to be a vector of Geminivirus. Pepper yellow leaf curl Indonesia virus (PYLCIV) is caused by Geminivirus, know to be transmitted by B. tabaci. It became an important disease in pepper and could cause 100% yield loss. Currently there is limited information concerning the genetic of B. tabaci associated with Geminivirus in Indonesia. It is therefore important to investigate the genetic identity of B. tabaci across different population. The aim of this research was to investigate the genetic identity of B. tabaci that were collected from pepper yellow leaf curl endemic area in the western part of Indonesia. Research activities include 1) sample collection of B. tabaci from pepper yellow leaf curl endemic area in west Indonesia; 2) single extraction of B. tabaci total DNA; 3) amplification of mitochondrial Cytochrome Oxidase I gene (mtCOI) fragmen with polymerase chain reaction (PCR); 4) mtCOI sekuencing 5) phylogenetic analysis of mtCOI fragmens from west Indonesian PYLCIV compared with some B. tabaci mtCOI deposited in National Center for Biotechnology Information (NCBI). Based on mtCOI fragment analysis, B. tabaci from PYLCIV endemic area were in one group belong to Asia I clusters. Genetic identity of B. tabaci from endemic area in Western Part of Indonesia were similar with polyatomic cladogram.

Abstract

Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) is one of the most important pests on cotton. Yield losses due to this pest can reach up to 70%. Pest control using the NPV has been proven to be effective in the field. However NPV isolates from different geographical locations could be showed variation in genetic and their biology. The purpose of this study was to compare morphology, biology, and molecular characteristics between three HearNPV isolates from cotton field in South Sulawesi, Central Java, and East Java. Scanning electron microscope (SEM) was used to look at morphological characters, whereas biological characters were observed by dipping shelled of young corn cob on each isolate suspension with a density of 2.5 x 103, 2.5 x 104, 2.5 x 105, 2.5 x 106, 2.5 x 107 POBs /ml and control then fed to the first instar larvae of H. armigera. Probit analysis was used to determine LC and LT. The molecular assay used polymerase chain reaction (PCR) with lef-8 gene. The results showed that the three isolates had the shape and size of polyhedra which was not significantly different with the mean diameter were 0.86 μm. The result showed that in 7 days post infection, HearNPV isolate from East Java was the most virulent isolates with the lowest LC50, which is 6.38 POBs/ml, but lowest LT50 value in 2.5 x 107 POBs/ml were showed both from East Java and South Sulawesi, which are 2.7 days post infection. Meanwhile, the DNA sequencing of the three isolates showed a high similarity (100% homology).

Abstract

Tetranychus urticae Koch and Tetranycus kanzawai Kishida are important pests of various crops of economically importance in Indonesia.  Acaricide are commonly used to control these mites. One of the alternative control methods is the use of phytoseiid predatory mites. Most of the phytoseiid mites that are used as biological control agents are exotic mites. For that reasons, it is necessary to study indegenous predatory mites that has the potential to be developed as biological control, such as N. longispinosus. The objective of this study was to determine the predation capacities of N. longispinosus on two red spider mites of T. urticae and T. kanzawai and the effect of predator densities to predator cannibalistic behavior. N. longispinosus were supplied with eggs and adults of T. urticae and T. kanzawai to determine the predation capacities. N. longispinosus were also supplied low number of T. kanzawai eggs as the prey at several predator densities to see its cannibalistic behavior. The results showed that the number of eggs of T. urticae dan T. kanzawai consumed by deutonymphs and adult females of N. longispinosus was higher than the adult female of T. urticae dan T. kanzawai. The number of eggs of T. urticae dan T. kanzawai consumed by adult female N. longispinosus was higher than by the deutonymphs. The number of eggs laid by adult females of N. longispinosus when feed on eggs of T. urticae and T. kanzawai was higher than those feed on adult female. Deutonymph and female adult stage of N. longispinosus showed cannibalistic behavior at several predator densities in low number of prey.

Abstract

Anagrus nilaparvatae Pang et Wang (Hymenoptera: Mymaridae) is a major egg parasitoid of brown planthopper, Nilaparvata lugens Stal (Hemiptera: Delphacidae). The purpose of this study was to examine the egg development type, the effect of host deprivation and feeding on the reproductive performance of parasitoid. Determination of the egg development type was done by dissecting females of A. nilaparvatae upon emerging. Adult females aged 0, 1, 2, 3, 4, 5, and 6 hours were killed in the freezer. Abdominal of wasp was dissected by micro pin. Mature egg of wasp were calculated and documented. Treatment of host deprivations were conducted by feeding 10% honey solution and depriving female parasitoids of host for 3, 6, 9, 12, and 18 hours consecutively. After treatments, female parasitoids were given hosts every day until the parasitoids died. Another group of parasitoids were given with water and treated with the same lenght of deprivation period. Results showed that the A. nilaparvatae egg development type is proovigenic. The egg maturation of parasitoid has been initiated since it first emerge with 75% mature eggs of potential fecundity. In the conditions provided 10% honey solution or water as feed, reproductive performance of A. nilaparvatae decreased with increasing duration of host deprivation period, include realized fecundity, parasitization rate, and longevity of female wasp. The decline in the reproductive performance was done by host deprivation for 9 to 18 hours. Longevity of female wasps varied from one to three days, with higher and lower values consecutively for 9 and 18 hours of host deprivation period.
